UNITED STATES A PATENT EEICEG CLAES W. BOMAN, OF NEW' YORK, N. Y., ASSIGNOR TO JOSEPH RECKEN- Y DORFER, OF SAME PLACE.

LEAD OR CRAYON HOLDER.

SPECIFICATION forming part of Letters Patent No. 267,643, dated November 14, 1882.

` Application tiled September 27, 1880. (Model.)

To all whom it may concern so that the jaws may be removed from or brought in contact with the lead, according to the direction in which they are moved with respect to the lead-holding tube.

My invention consists in combining with the sheath or handle and the lead-holding tube one or more jaws which extend into one or more jaw-admitting openings on or in the line of said tube, so as to grasp the lead, said jaw or jaws and lead-containing tube being longitudinally movable with respect toone another, so that the lead may be grasped or released according to the position which said parts occupy relatively to one another, substantially as hereinafter set forth.

It further consists in combining with the said lead-holdingjawor jaws a clamp or retaining-jaw carried by and moving with the tube and operatingto intermittently clamp thelead in the tube, its clamping action taking place when the leadholdingjaw is raised from the lead, the ei'ech'when the tube is lon-l gitu'dinally reciprocated, being to produce a regular forward feed ofthe lead; and Ifurther so arrange said parts that by moving the tube sufficiently far forward both jaws` or sets of jaws will be raised from the lead, leaving the latter free to move in the lead-receiving tube as though there were no clamp or retainingjaw.

The nature of my invention and the manner in which the sameis or may be carried into the jaws in the dilerent positions they assume with respect to the lead-holding tube and to one another at different times during the forward and back movement ot' said tube. Figs. 6, 7, 8, and 9 are views of a modification hereinafter referred to. enlarged scale.

The handle or case A is tubularand of the usual construction, being provided with the contracted nozzle or tip a.

B is the longitudinally-movable lead-containing tube or receiver, extending at the front into the front openin g of the tip and attached at the rear'to the cap I). The spring c., confined between the cap and the end of the handle, serves to retract the tube, and by pressing on the cap the tube can be moved. forward against the stress ofthe retracting-spring.

Inside of and connected with the sheath or handle so as to move therewith is a lead-grasping jaw, al. This jaw at its frontend enters an opening, e, in the lead containing tube, so as to bear on the lead therein. For this purpose the jaw is preferably made of spring metal, and so constructed and arranged as normally to press inwardly or toward the tube. When the parts are in normal position the jaw is in the opening e and bears on the lead with suftcient force to hold it. By pressing on the cap, and thus moving the lead-holding tube forward against the stress of the retractinglsprin g, the

All the figures are on an opening e will be carriedV forward beyond the jaw, and the latter will be lifted by the solid part of the tube, the rear edges of the opening ebein g preferably beveled orinclined, as shown, s0 that the jaw-.can ride up on them easily. When pressure on the cap is removed the retracting spring draws the tube back andthe jaw oncemore enters the opening c and resumes its hold on the lead.

One or more lead-graspingjaws may be used, as desired, and it or they may be variously arranged to accomplish the object I have in view. For instance, it is not necessary that the jaw should be positively fastened to the sheath, as indicated in Figs. 6 to 9, inclusive, in which the jaw cl is carried by a sleeve, d, mounted loosely on the lead-tube B, between the front of the tip a and a loose washer, a', at the front end of the handle A, on which the tip is fastened. The sleeve is held between these two points so as to be incapable of appreciable ject in partof separate application for Letters Patent.

The arrangement of the jaw shown in Fig. 6 is advantageous, inasmuch as it permits the jaw to turn with the tube should the latter be twisted or rotated by means of the cap.

It desired, I can combine with the lead-graspingjawor jaws an instrumentality for feeding forward the lead when desired, and this additional featureis shown embodied in the holder illustrated in Figs. l to 5, inclusive. The additional device required for this purpose consists of an intermittently-acting clamp or retaining-jaw, lettered j', which is attached to and moves with the tube B, and is preferably of spring metal, with its free end extending over or into the opening e, but normally out of contactwith the lead. The clamp-jawisformed, as shown in the drawings, with its acting end projecting laterally from its shank toward the shank of the grasping-jaw d. The graspingjaw is similarly formed, as shown in Fig. l,

and the laterally-projecting portions f2 d2 of two the jaws are in line with one another, as shown, so as to lie in the same path. The parts f2 d2 slope upwardly to the rear. When the parts are in normal position the clamp-jaw is out of contact with the lead and in rear of the grasping-jaw, as indicated in Figs. l and 2. When the tube B is pushed forward the clamp-jaw f2 passes under the graspingjaw 612 with the eit'ect of raising the latte-r from the lead and depressing the former (the clamp) upon thelead, which is thereby clamped. in and compelled to move forward with the tube so long as the clamp-jaw is beneath the graspingjaw, as indicated in Fig. 3. As soon as the tube moves far enough forward to clear the clampjaw from the grasping-jaw the former will rise from the lead and thelatter will descend upon the lead or into the rear portion of the opening e, as indicated in Fig. 4, so that when pressure is removed from the cap and the tube is retracted the lead carried forward with the tube by the action of the clamp will now be held by the grasping-jaw and prevented from moving back with the tube,while the clam p-jaw in its rearward movement rides over the grasping-jaw, as indicated in Fig. 5, and returns to its normal position. 'Ihus each forward and backward movement ofthe tube will cause the lead to advance adeiinite distance, determined by the extent of saidmovement and the length of that portion of the movement during which the clamp-jaw is held down by the graspingjaw on the lead. By moving the tube forward the full distance needed to bring the grasping- `jaw upon the rear portion of the beveled edges bounding the rear ofopening e, the jaw will be raised far enough to entirely'release the lead, so as to permit it to freely be moved out of or into the tube to any extent desired.

I do notdcsire to restrict myself to the use of the clamp and graspingjaws conjoiutly, for it is manifest, as hereinbefore described, that the grasping jaw or jaws alone may be used,

the'clamp-jaw being an accessory, which can be employed in case it is desired to have a' definite regular feed for the lead.

It is manifest, of course, that the clamp-jaw can also be employed, il' desired, witha grasp-v ing-jaw arranged as shown in Fig. G. The said the opening therein far enough to grasp the lead, and when the tube is moved in the opposite direction will be removed from the opening far enough to release the lead. I therefore do not restrict myself` to the details herein shown and described in illustrationof my iuvention; but

What I here claim, and desire to secure by Letters Patent, is-

1. rIhe combinatiomwith the sheath or handle and the longitudinally-movable lead-containing tube, of a lead-'graspingjaw inside of and connected with the sheath, extending into the interior of the tube through an openingtherein, so as to have contact with the lead, andoperated by the tube, according to the direction of its movement, to clamp and release the lead, substantially as hereinbefore set forth.

2. In a lead or crayon holder, the combination of a sheath or handle, a lead tube or receiver within said handle, a lead-graspin g jaw longitudinally movable with respect to said tube and adaptedto enter an opening therein, a spring for moving said parts to the position in which the jaw clamps the lead, and a pressure-cap by which the parts are moved with respect to one another against the stress of the IOO IIO

spring to release the lead, substantially as hereand earriedwbyaJ sleeve whioh eneireles the tube and `is held between the noz-zlefor tip and lshoulder-ou the handle, as shown and described. i

5 5. The combination of the handle or sheath, the longitudinelly moving lead f containing tube, formed with jaw-admitting opening, as

described, the grasping-jaw, and anintermit-` tently--operating 1clamp or retaining-jew oar- Io ried'` by the tube, these parts being combined and arranged to operate jointly, substantially as and for the purposeshereinbeforeset forth.

, @The combination, with" the longitudinallymovable lead-earryin g tube, of a lead-graspin g r 5 jaw carried by the sheath and provided 4with zr projection that alternately passes under and rides over a projection` carried byand moving with the said tube, whereby said jaw is caused to release the lead when the tube moves for- CLAES W.
